Be it known that I, BENJAMIN LOMAX HARDY, a citizen of the UnitedStates, re-

siding at Mobile, in the county of Mobile and tate of Alabama, haveinvented certain new and useful Improvements in' a Rotary GasolineMotor, of which the following is a specification.

This lnvention relates to rotary gasoline motors and 1t conslsts 1n thenovel features hereinafter described and claimed.

'. tons may pass.

An object of the invention is to provide a motor of the character statedwhich is of simple and durable structure having its parts and featuresso assenibled and arranged as to affect a preliminary compression of thegases or mixture and means for passing the fuel in compressed form intoan explosion chamber in which a series of istons is mounted forrotation.

W ith this object in view the motor in-- cludes a shaft carrying aseries of pistons and passing transversely through the explosion chamberand a compression cylinder having a piston movably mounted thereon,means being provided for operativelytake which connects with thecompression chamber and means are provided uponthe shaft for opening thevalve to permit the gas to enterthe compression chamber as the piston ismoving upon its intake stroke. the accompanying drawings Figure 1 is ato plan view of the motor with parts thereof in section.

Figure 2 is a similar view of the motor showing the piston at the end ofits intake stroke. a

Figure 4 is atransverse sectional view through the explosion-chamber ofthe motor.

Figure 5 is a transverse sectional viewthrough the compression chamberof the motor. a A

The rotary gasoline motor mmpr ses a base 1 having a standard 2 mountedthereon and in which a shaft 3 is journaled for rotation. An explosionchamber4 is mounted upon the base 1 and a shaft 5 passes transverselythrough the explosion chamber. and is provided at one end with a beveledpinion 6 which meshes with a beveled pinion 7 mounted upon the shaft 3.A compression chamber 8 is mounted upon the base 1 and a gas conduit 9communicates with one end portion thereof. A spring'pressed valve 10 isarranged to con trol the passage way through the conduit 9 and the stemof the said valve projects beyond the side of the conduit. A star wheel11 is mounted'upon the shaft 5 and is arranged so that its peripheralsurface will wipe over the stem of the valve 10 as the shaft 5 isrotated. A disk 12 is mounted upon the shaft 5 and is housed within theintermediate portion of the explosion chamber 4. A series of spacedpistons 13 are mounted upon the periphery of the disk 12 and are housedwithin the outer portion of the explosion chamber-4.

The explosion chamber 4 is provided with:

an exhaust port 14. 4

A piston 15 is slidably mounted in the compression chamber 8 and anabutment 16 is fixed to the inner face of the piston 15. The abutment 16is provided at its side with er 4. The abutment 16 is further providedatone edge with a recess 18 through which the pistons 13 may pass as thedisk 12 rotates.

A rod 19 is connected at one end with the piston 15 and passes throughthe end wall of the compression chamber 8. A

crosshead 20 -is connected with the outer a duct 17 adapted toestablish, at certain end of. the rod 19' and rods 21 are pivotal- 1yconnected at one end with the opposite ends of the cross head 20 andpivotally connected at their other ends" with a cross bar 22 which ispivotally and eccentrically connected with a disk 23 mounted upon theshaft 3. An suitable means (not shown) maybe provided for firing thecharges of gas in the explosion chamber and such means may be in theform of usual spark ph igf.

e operationof the motor is as follows Assuming that the-shaft 5 has beenstarted in rotation, the beveled inions 6 and 7 rotate' the disks 23where ythe bars 21 are moved longitudinally and the rod 19 and piston 15are reciprocated. As the piston 15 moves toward the valve 10, the gaseswhich have been receivedwithin the compression chamber 8 are compressedand when the ducts 17 move into register with the interior of the exlosion chamber 4, the solid portion of the a utment 16 is disposedcompletely across the explosion chamber 4 and the said gases are thenexploded in the chamber 4 whereby they expand and operate against theend of one of the pistons 13 and augment the rotary movement of theshaft 5. After the explosion takes place, the valve 16 moves from theposition shown in Figure 1 of the drawing to the position shown inFigure 2, whereby one of the pistons 13 may move through theclearancespace provided at the recess 18 and the piston 15 is retractedupon 5 s intake stroke whereby the gas is drawn in through the conduit 9into the chamber 8.

As the shaft 5 rotates the pointed end portions of. the stellaform wheel11 engage the stem of the valve 10 whereby the said valve is moved to anopen position to permit the flow of the gas from the conduit 9 into thecompression chamber 8. The points of the wheel 11 are so timed withrelation to the movement of the piston 15 that the valve is opened whilethe piston is moving upon its intake stroke and as the piston moves uponits compression stroke the point of the wheel 11 passes beyond the stemof the valve 10 whereby the said valve may close under the influence ofthe impelling spring and consequentl communication between the interioro the compression chamber 8 and the conduit 9 is interrupted and thegases compressed in the chamber 8 by the forward movement of the piston15 and when the end of the duct 17 comes into register with the interiorof the explosion chamber 4, the said compressed gas is expelled from thecompression chamber by the action of the piston 15 into the explosionchamber.

Having thus described the invention, what I claim is a 1. A rotary motorincluding an explosive chamber, a shaft journaled transversely therein,pistons operatively connected with the shaft and housed within theexplosive chamber, a compression chamber, a piston.

mounted for reciprocation in the compression chamber, means operativelyconnectin the piston with said shaft, a valve controll conduit forleading the fuel into the compression chamber, means carried by theshaft for operatin the valve, a plate atutment carried by t e lastmentioned piston and adapted to move transversely across the explosionchamber and having a duct formed in one longitudinal edge adapted totransmit the gas from the compression chamber into the explosion chamberand provided with a recess through which the first mentioned pistons maypass. Y

2. A rotary motor including in combination, a base, a shaft 'ournaledtransversely of the base at one en thereof, an explosion chamber mountedat the other end of the base, a shaft journaled transversely through theexplosion chamber and longitudinally of the base, gearing connecting thetwo shafts, a compression cylinder mounted longitudinally of the basebetween the first mentioned shaft and the explosion chamber, pistonsoperatively connected with the second shaft and housed within theexplosion chamber, a second piston mounted for reciprocation in thecompression cylinder, means oper atively connecting the second istonwith the first shaft, a valve controlled conduit for leading the fuelinto the compression cylinder, means carried by the second shaft foroperating the valve, a plate abutment carried by the second piston andadapted to move transversely across the explosion chamber and having aduct formed in one longitudinal edge extending from the piston andterminating at an intermediate point of the abutment and adapted totransmit the gas from the comression cylinder into the explosion chammaypass.
